Flower (c)1986 Komax
       (c)1986 Sega/Alpha (Sega game number 834-5998)

 - Driver by InsideOutBoy

There is a PCB picture that shows two stickers, the first
      says "Flower (c) 1986 Clarue" while the second one
      is an original serial number tag also showing "Clarue"


todo:

fix sound
improve interrupts
